The little British computer that's taken the world by storm! It's the ideal way to take your first steps in coding, and our range of kits, add-ons, and accessories make it fun to learn with Raspberry Pi.

Arduino and other Arduino-compatible microcontrollers are perfect when you need a small, rock-solid controller for your project. Program them, pop them into your project, and they'll happily run forever.

Kits are great all-in-one bundles that make perfect gifts, holiday projects, or just as a way to get started with something. Most of our range of kits blend creativity and making with electronics and coding.

Breakouts add handy functions to your microcontroller, be it a Raspberry Pi, Arduino, or something else. They tend to be dedicated to just one or a couple of functions, like audio output, motor driving, or sensors, but can be built up into larger projects.

This is where you'll find all sorts of handy bits and bobs for your projects, or just to stock up your kit box. Wires, LEDs, speakers, power supplies, header pins, sensors, integrated circuits, you name it!

Lithium Ion Battery Pack

Give your project some grunt with these lithium ion battery packs! Made from balanced 2200mAh cells connected in parallel including protection circuitry.

The ultimate range of high-quality lithium ion battery packs - pick whichever offers the best performance/size for your project. These little guys pack a huge amount of energy - we've tested each version to ensure the datasheet specs are accurate and the safety features kick in when needed.

Please note: Lithium ion batteries must be treated with respect and charged/discharged within the parameters listed in the datasheet, you should never dent, bend, puncture, crush, or otherwise damage them. You should only consider these kinds of batteries for your projects if you've done your research and understand the risks.

All our batteries come with a 100mm lead terminated with a standard 2-pole JST connector. They also include protection circuitry to ensure that they are not over discharged/charged and are protected from short-circuits but you should still take care when using them.

﻿Features

3.7V nominal voltage

100mm JST terminated lead

Come 30% pre-charged for longer life storage

4.2V charging cut-off and 2.4V emergency discharge cut-off

Short circuit protection

You should avoid discharging these batteries beyond 3.0V - the emergency protection circuitry will kick in at 2.4V. If the battery bulges or is physically damaged it should be discarded. Do not charge unattended.

This battery holder connects 3 AA batteries together in series for powering all kinds of projects. The box is compact, and 3 AA's add up to about 3.3-4.5V, a very similar range to Lithium Ion/polymer (Li-Ion) batteries, plus it has a nifty on-off switch. Read more...
